Improvement in sulky-plows



B E N JAM-.rNifs nu s s E n; 'onfr s iiD-NLE Y` IMPROVEMENT IN suLKY-PLOWS.

Specification forming part of Letters Patent No. 80,427, dated July 28, 1868,.

f To all whom it may concern:

reference being had to the annexed drawings, making a part of. this specification, in which- Figure lis an elevation of the right side, the right wheel being removed. Fig. 2 is a plan, the seat being removed. Fig. 3 is a section of the right axle-crank, showing the adjacent parts in elevation7 and exhibiting the construction and operation of the devices for lifting and adjusting the plow.

The object of this invention is to simplify the construction oi sulky-plows, so as greatly to reduce their cost, while yet enabling them to be capable of easy operation, of ready adjustment, and of yielding to immovable obstacles without breaking.

In the drawings, A represents the draftpole; B B, the draft-wheels; C, the axle-tree, which is provided with a double crank, c, at itscenter; D,the mold-board; and E F curved iron standards, one attached to each side of the draft-pole, and extending from its rear end back, then down, and then, at their lower ends, slightly forward, where they are bolted alongside of each other to the rear side of the mold-board, near its forward edge, support- `ing it in the manner clearly shown in Figs. l

and 2.

G is the driyers seat, supported upon arched standards g g, which are pivoted to the axle just outside of either arm of the crank c, and steadied in its position by a rod, H, which extends forward from the top of the standards g g, and is hinged to a short vertical post, I, which itself is hinged to the upper side of the pole A, so that, as the crank c rises or falls, the seat G always maintains its proper position, the movement of the post I counterbalancing the movement of the crank.

VIn Fig. 2, the seat G is removed, the points a a a showing where the section is taken.

From the forward or inner extremity of one of the crank-arms a projection, fm, extends forward slightly beyond the line of the axle C, and has a lever, L, hinged to it, and extending forward, terminating-in a foot-rest, l, and workin g in a ratchet-guide, K, by which it can be confined at any elevation, and which causes it to travel up and down in a vertical path. The lever has a shoulder, fn, which sets against the ,fsquare end of the projection m when the lever-handle is thrown down, and thus forces the part m down with the lever and throws the crank-pin up, elevating the rear end of the pole A, which is supported upon the crank-pin, and thus raising the plow out of the ground.

0n the other hand, there is nothing in the nature of the joint by which the lever is hinged to the part m to prevent the rear end of the,

crank from being thrown up without raising the lever, as shown in Fig. 3. Thus, when the forward end of the lever is fasteneddown by the rack K, if the plow should strike an immovable obstacle, it will rise, throwing up the crank without detaching the lever from its notch in the rack, and again, when the'obstacle has been passed, dropping to its proper position. The device thus works easily and automatically without danger of breaking.

This method of construction enables me to entirely dispense withthe old-fashioned landside, constructing my plow simply of a moldboard and point, or a pointed mold-board attached to the two supporting-standards E F.

I thus avoid at the same time the great weight of the land-side and its friction against the ground, as it is forced through it, enabling me to construct my plow at about half the expense of the old one, while it has not much more than half its weight and works with greatly diminished friction against the soil;

The whole instrument is exceedingly simple and cheap in construction, having less parts `toget out of order when working than any sulky-plow yet brought into use. Its simplicity of construction' enables it to be made very light, so that it can be handled easily under all circumstances; and from this fact, which is one of its most marked and conspicuous characteristics, I have given it the name of Slussers Light-Draft Sulky-Plow.77 V

Having thus described my invention, what I claim as new, and desire to secure by Letters l'fThe combination 'of the lever L, having.

the shoulder n, W-i-'th the crank c, having the projection m, and supporting the standard to -Which the plow is attached, when the several parts are connected andarranged so as to operate together, substantially in the manner and for the purpose specified.

2. The combination ofthe crank c, standardsg g, seat G, rod H, and hinged post I, sah stantially as and for the purpose described.

3. Supporting the plow upon two standards, 1 E F, bent in the form and attached to the rear vside of the plow, in the manner described.
